The present invention relates to a device lighttowards the entrance increasing the atfor catching insects taking advantage of tractiveness for the insect, but making it theirhabits to perch upon transparent, diadiflicult for the latter to get out. A 1 phanous: or bright surfaces illuminated Said series of ducts which may be consid- 5 naturally or: artificially, and the habit to fly ered as channels in miniature and which form in all directions when meeting with any obopen angles at the summit with their reflecstacle in their way. 7 tor, are arranged in a labyrinth-like shape In view of this, the special device which for which also loose partition-walls of differconsistsin a kind of box which may be given ent shaps and measurements are used constiall possible shapes with or without fixed or tuting units of various forms,dependingupon removable 'cover being in the latter case the, dimensions and forms of the traps and closed by the surface. to which same is apwhich may be, as set forth, either plain or plied, is provided, at the level of said surface, broken or bent, according to the surface inwith an entrance to its interior constituted tended forreceiving the trap box. l
